Answer:

99.85%

Step-by-step explanation:

The lifespans of meerkats in a particular zoo are normally distributed. The average meerkat lives 10.4 years; the standard deviation is 1.9 years.

Use the empirical rule (68-95-99.7%) to estimate the probability of a meerkat living less than 16.1 years.

Solution:

The empirical rule states that for a normal distribution most of the data fall within three standard deviations (σ) of the mean (µ). That is  68% of the data falls within the first standard deviation (µ ± σ), 95% falls within the first two standard deviations (µ ± 2σ), and 99.7%  falls within the first three standard deviations (µ ± 3σ).

Therefore:

68% falls within (10.4 ± 1.9). 68% falls within 8.5 years to 12.3 years

95% falls within (10.4 ± 2*1.9). 95% falls within 6.6 years to 14.2 years

99.7% falls within (10.4 ± 3*1.9). 68% falls within 4.7 years to 16.1 years

Probability of a meerkat living less than 16.1 years = 100% - (100% - 99.7%)/2 = 100% - 0.15% = 99.85%

Answer:

65.30

Step-by-step explanation:

1. 50x4=200

2. 200x65=13,000

3. 13,000 + (15x4)

4. 15 x 4 = 60

5. 13,000 + 60

6. 13,060/200 = 65.3

Your average cost per racket including delivery charges is $65.30.

First step is to calculate the cost of 200 rackets

Cost of 200 rackets= 200 ×$65

Cost of 200 rackets= $13,000

Second step is to calculate the total delivery fee

Total Delivery fee= 15 × 4

Total Delivery fee=$60

Third step is to calculate the total cost including delivery cost

Total cost including delivery cost=$13,000 + $60

Total cost including delivery cos = $13,060

Fourth step is to calculate the Average cost

Average cost per rackets=$13,060/200

Average cost per rackets=$65.30

Inconclusion the average cost per racket including delivery charges is $65.30.

Answer:

32.8%

Step-by-step explanation:

Container A:

Diameter = 30 feet

Radius = diameter/2 = 30/2

= 15 feet

Height = 16 feet

Volume of a cylinder = πr²h

= 3.14 * 15² * 16

= 3.14 * 225 * 16

= 11,304 feet ³

Container B:

Diameter = 22 feet

Radius = diameter / 2

= 22/2 = 11 feet

Height = 20 feet

Volume of a cylinder = πr²h

= 3.14 * 11² * 20

= 3.14 * 121 * 20

= 7598.8 feet ³

what is the percent of Container A that is full after the pumping is complete?

Container A - container B

= 11,304 feet ³ - 7598.8 feet ³

= 3,705.2 feet ³

percent of Container A that is full after the pumping is complete = 3,705.2/11,304 × 100

= 0.328 × 100

= 32.8%

percent of Container A that is full after the pumping is complete = 32.8%

Answer:

3:00

Step-by-step explanation:

If the minute hand is pointing straight up, it means that the time is at an exact hour (ex. 1:00, 2:00, not 1:30, etc.).

If the angle between the hour and the minute hand is 90 degrees, then we know that the time is either 3:00 or 9:00.

However, because the time must be between 1:00 and 5:30, it must be 3:00.

Answer:

12.5%

Step-by-step explanation:

Given data

Number of bicycles sold last year= 655

Number of bicycles sold this year= 582

%percent change= Iniitial -FInal/initial *100

%percent change= 655-582/582*100

%percent change= 73/582 *100

%percent change=0.125 *100

%percent change=12.5%

Hence the percent change is 12.5%

Answer:

midpoint is (-15/2, -15/2)

Step-by-step explanation:

Finding the coordinates of the midpoint is easy.  All you have to do is find the average of the x-coordinates and the average of the y-coordinates of the endpoints of the segment.

So, in your case

(-8 - 7)/2 = -15/2 is the x-coordinate

(-7 - 8)/2 = -15/2 is the y-coordinate

Therefore, the midpoint is (-15/2, -15/2)

Answer:

(-7.5, -7.5)

Step-by-step explanation:

Remember that the formula is (x1+x2/2, y1+y2/2)

So, we know that -8 is x1 and -7 is y1. We also know that -7 is x2 and -8 is y2.

Lets plug this into our formula and see what we get.

(-8+-7/2, -7+-8/2)

Now lets find the x in the midpoint.

-8+-7/2 is equal to -15/2. This makes x equal to -7.5.

Now lets find the y in the midpoint.

-7+-8/2 is equal to -15/2 as well. This makes y equal to -7.5.

Now we can tell that the coordinates for midpoint will be:

(-7.5, -7.5)

MISCONCEPTIONS:

Always remember that midpoint is nothing like slope. The mid point is something you can point on a graph, wheareas slope is a function that can be lined on a graph.

The formulas for the two things are different as well. Slope is y/x, where you subtract the ys and xs from each other. In a way, midpoint is the exact opposite, which is adding the xs and ys together.

I hope this helps ;)

Answer:

1/16

Step-by-step explanation:

Given the expression;

[tex]x^2+\dfrac{1}{2}x[/tex]

To find a constant that will make it a perfect square, we will use the square if the half of coefficient of x

Coefficient of x = 1/2

half of Coefficient of x = 1/2*(1/2)

Half of Coefficient of x = 1/4

square of the half of coefficient of x = (1/4)^2

square if the half of coefficient of x = 1/16

hence the constant that will make it a perfect square is 1/16
